Franklin Foer: The Mueller probe was an unmitigated success
Summer 2016. Russian outreach to the Trump Campaign continued into the summer of 2016, as candidate Trump was becoming the presumptive Republican nominee for President. On June 9, 2016, for example, a Russian lawyer met with senior Trump Campaign officials Donald Trump Jr., Jared Kushner, and campaign chairman Paul Manafort to deliver what the email proposing the meeting had described as "official documents and information that would incriminate Hillary." The materials were offered to Trump Jr. as "part of Russia and its government's support for Mr. Trump." The written communications setting up the meeting showed that the Campaign anticipated receiving information from Russia that could assist candidate Trump's electoral prospects, but the Russian lawyer's presentation did not provide such information.
Days after the June 9 meeting, on June 14, 2016, a cybersecurity firm and the DNC announced that Russian government hackers had infiltrated the DNC and obtained access to opposition research on candidate Trump, among other documents.
In July 2016, Campaign foreign policy advisor Carter Page traveled in his personal capacity to Moscow and gave the keynote address at the New Economic School. Page had lived and worked in Russia between 2003 and 2007. After returning to the United States, Page became acquainted with at least two Russian intelligence officers, one of whom was later charged in 2015 with conspiracy to act as an unregistered agent of Russia. Page's July 2016 trip to Moscow and his advocacy for pro-Russian foreign policy drew media attention. The Campaign then distanced itself from Page and, by late September 2016, removed him from the Campaign.
July 2016 was also the month WikiLeaks first released emails stolen by the GRU from the DNC. On July 22, 2016, WikiLeaks posted thousands of internal DNC documents revealing information about the Clinton Campaign. Within days, there was public reporting that U.S. intelligence agencies had "high confidence" that the Russian government was behind the theft of emails and documents from the DNC. And within a week of the release, a foreign government informed the FBI about its May 2016 interaction with Papadopoulos and his statement that the Russian government could assist the Trump Campaign. On July 31, 2016, based on the foreign government reporting, the FBI opened an investigation into potential coordination between the Russian government and individuals associated with the Trump Campaign.
Separately, on August 2, 2016, Trump campaign chairman Paul Manafort met in New York City with his long-time business associate Konstantin Kilimnik, who the FBI assesses to have ties to Russian intelligence. Kilimnik requested the meeting to deliver in person a peace plan for Ukraine that Manafort acknowledged to the Special Counsel's Office was a "backdoor" way for Russia to control part of eastern Ukraine; both men believed the plan would require candidate Trump's assent to succeed (were he to be elected President). They also discussed the status of the Trump Campaign and Manafort's strategy for winning Democratic votes in Midwestern states. Months before that meeting, Manafort had caused internal polling data to be shared with Kilimnik, and the sharing continued for some period of time after their August meeting.
